They can allow small, simple AC meter movements to indicate extremely high voltages and currents in power systems with accuracy and complete www. Usman Sir. October State the applications of ac potentiometers.

State the use of Wein bridge. This internal resistance may be of interest to measure, and so the Wien bridge attempts to do so by providing a balancing imped ance that isn't pure either: www. However, as it would create a direct current path for stray curren. Let's look at different ways of making measurements.

Ammeters are connected in series in the circuit whose current is to be measured. State the balance equation used in bridge methods. Astronomical u. Yugandhar Veeramachaneni. Therefore voltmeters should have a high electrical resistance so that they cause a small voltage drop and consequently absorb small power.

Check our new membership plans and prices! Electrical voltage and current are two important quantities in an electrical network. The voltage is the effort variable without which no current is available. It is measured across an electrical circuit element or branch of a circuit. The device that measures the voltage is the voltmeter. The current is the flow variable that represents net motion of the charged particles electrons in solids, ions in a liquid in a given direction. The product of the two yields the instantaneous electrical power.
